\title{Dispersion Test of CSR for Split Point Pattern Based on
       Quadrat Counts}
\description{
  Performs a test of Complete Spatial Randomness
  for each of the component patterns in a split point pattern,
  based on quadrat counts.
  By default performs chi-squared tests; can also perform
  Monte Carlo based tests.
}
\usage{
\method{quadrat.test}{splitppp}(X, ..., df=NULL, df.est=NULL, Xname=NULL)
}
\arguments{
  \item{X}{
    A split point pattern (object of class \code{"splitppp"}),
    each component of which will be subjected to the goodness-of-fit test.
  }
  \item{\dots}{Arguments passed to \code{\link{quadrat.test.ppp}}.}
  \item{df,df.est,Xname}{Arguments passed to \code{\link{pool.quadrattest}}.}
}
\details{
  The function \code{quadrat.test} is generic, with methods for
  point patterns (class \code{"ppp"}), split point patterns
  (class \code{"splitppp"}) and point process models
  (class \code{"ppm"}).

  If \code{X} is a split point pattern, then for each of the
  component point patterns (taken separately) we test 
  the null hypotheses of Complete Spatial Randomness,
  then combine the result into a single test.

  The method \code{quadrat.test.ppp} is applied to each
  component point pattern. Then the results are pooled using
  \code{\link{pool.quadrattest}} to obtain a single test.
